Description

Дл  автоматического контрол  и регулировани  температуры электрического нагрева металлов примен ют электронные реле времени, основанные на периодическом разр де емкости через электронную ламну.For automatic control and regulation of the temperature of electrical heating of metals, electronic time relays are used, based on the periodic discharge of capacitance through an electronic lamina.

Известные подобные реле не обеспечивают достаточной точности регулировани  температуры из-за вли ни  колебаний напр жени  на нагревательном устройстве.Known such relays do not provide sufficient temperature control accuracy due to the influence of voltage fluctuations on the heating device.

Дл  устранени  указанного недостатка предлагаетс  в качестве разр дной емкости при,мен ть два последовательно соединенные конденсатора , один из которых имеет нелинейную характеристику. Эти конденсаторы зар жаютс  выпр мленным напр жением, снимаемым с подключенного через выпр митель к нагревательному устройству делител  напр жени , имеющего сопротивление с нелинейным коэффициентом сопротивлени .To eliminate this drawback, it is proposed as a discharge capacity for changing two series-connected capacitors, one of which has a non-linear characteristic. These capacitors are charged with a rectified voltage taken from a voltage divider connected through a rectifier to a heating device, having a resistance with a non-linear resistance coefficient.

На чертеже изображена электрическа  схема иредлагаем1)го .The drawing shows the electrical circuit and proposed 1) th.

Напр жение, снимаемое с нагревательного устройства, подводитс  через полупроводниковый выпр митель 7 к делителю напр жени , состо щему из двух сопротивлений 2 и 5.The voltage taken from the heating device is supplied through a semiconductor rectifier 7 to a voltage divider consisting of two resistances 2 and 5.

Сопротивление 2  вл етс  обычным линейным сопротивлением, а сопротивление 3-нелинейное с отрицательным коэффициентом сопротивлени .Resistance 2 is the usual linear resistance, and resistance is 3 non-linear with a negative resistance coefficient.

Напр жение, снимаемое с лииейного сопротивлени  2, подаетс  через переменное сопротивление 4 на два последовательно включенные конденсатора 5 W. 6.The voltage taken from the line resistance 2 is fed through the variable resistance 4 to two series-connected capacitors 5 W. 6.

Конденсатор 5  вл етс  варикопдом с отрицательным коэффициентом зависимости диэлектрической посто нной от напр жени .Capacitor 5 is a varicopd with a negative voltage-dielectric constant.

Конденсатор 6 имеет линейную зависимость между током и напр жением .Capacitor 6 has a linear relationship between current and voltage.
